This paper presents the results of a regression analysis of the influence of the chemical composition, i.e., the alphagenic (Si and Cr) and gamagenic (Mn and Ni) elements on the tensile properties of the steel. The results of the analysis are the equations with which we can calculate the strength for a given chemical composition when a measurement is disabled. The regression analysis showed that the strength of the steel can be increased with an increased amount of alphagenic elements and that the influence of Mn on the strength depends on the Si amountNitronic 60 (UNS S21800) je visoko legirano avstenitno nerjavno jeklo s povečano vsebnostjo mangana in silicija ter z dobrimi mehanskimi in korozijskimi lastnostmi. Ta članek predstavlja rezultate regresijske analize vpliva kemijske sestave, to je alfagenih (Si in Cr) in gamagenih (Mn in Ni) elementov na natezno trdnost jekel. Rezultati analiz so enačbe, s katerimi lahko izračunamo trdnost jekla iz dane kemijske sestave, če meritev ni mogoča. Regresijska analiza je pokazala, da se trdnost povišuje z naraščanjem vsebnosti alfagenih elementov in tudi, da je vpliv Mn na trdnost odvisen od vsebnosti SiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
